The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, users can be required to make a circle of beams at a certain height, arranged on three sides, and disconnected on one side of the elevator entrance. The distance between the center heights of the beams depends on the product model, and should not exceed 2500mm. The beam height should be 300mm,Qi geqiVilla small household elevator, and the thickness should be the same as the wall. The lower ring beam is 500-1500mm away from the bottom of the pit, and the higher ring beam is 200-500mm away from the lower surface of the shaft roof. The completed framework with a solid brick structure shaft can be equipped with steel plywood at the position of the fixed guide rail support frame. The position and size of the plywood are provided by the elevator, and the user is responsible for providing materials and construction. If the shaft structure is made of hollow bricks without ring beams, steel beams can be considered to be added between the frames for rectification.

.Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device, like braking to stop.
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.
When the normal power supply is cut off, the lighting inside the non fire elevator has no power, while there is still lighting inside the fire elevator.

Tower style residential buildings above; Residential units and corridors with twelve or more floors; Other Class II public buildings with a building height exceeding 32 meters; High rise buildings with elevators exceeding 32 meters in height; The functional fire elevator has a front room. The area of the independent fire elevator front room is: the front room area of the residential building is greater than 5 square meters; The front room area of public buildings and high-rise factory (warehouse) buildings is greater than 6 square meters. When the front room of the fire elevator is shared with the smoke proof staircase, its area is: the area of the shared front room in residential buildings is greater than 6 square meters and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than 10 square meters.
When accidentally trapped in an elevator, one should remain calm, press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons, and patiently wait for rescue.
Qi geqi.2. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space,Qi geqiStage hydraulic lifting platform, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, such as explosion-proof, anti-corrosion, and heat-resistant elevators
